He agreed it was right that I told him, but he still didn't want to know.

I can relate to this. Ignorance was bliss, but at the same time, I am glad I found out. Yes, it seems divergent thinking. Not sure how that helps you exactly except I guess to know that your husband isn't the only human being to ever feel this way.

Anyway... your initial post was ONE week ago. Talk about a whirlwind, huh? I can only imagine the emotional roller coaster you've ridden the last week.
Here's my suggestion (emphasis on 'my' and 'suggestion')... take a breath. Several breaths. Let everyone sit with the info they have and talk about it if/when they find it necessary up to the point they/you are comfortable. If a bit of time goes by and you feel nobody seems to be addressing the matter at hand (esp. dh), then maybe try to encourage some dialogue there.
